USAF DATCOM

The USAF Stability and Control DATCOM (Data Compendium) was compiled between 1960 and 1978 by the McDonnell Douglas Corporation in conjunction with the engineers at the Flight Dynamics Laboratory at Wright-Patterson Air Force Base. DATCOM provides a systematic summary of methods for estimating basic stability and control derivatives. The book is intended to be used for preliminary design purposes before the acquisition of test data. The use of reliable test data in lieu of DATCOM is always recommended. However, there are many cases where DATCOM can be used to advantage in conjunction with test data.

A spectrum of methods is presented, ranging from very simple and easily applied techniques to quite accurate and thorough procedures. Comparatively simple methods are presented in complete form, while the more complex methods are often handled by reference to separate treatments. Tables which compare calculated results with test data provide indications of method accuracy. Extensive references to related material are also included.

The major classification of sections in DATCOM is according to type of stability and control parameter. This classification is summarized below:

Guide to DATCOM and Methods Summary

General Information

Effects of External Stores

Characteristics at Angle of Attack

Characteristics in Sideslip

Characteristics of High-Lift and Control Devices

Dynamic Derivatives

Mass and Inertia

Characteristics of VTOL-STOL Aircraft

DATCOM methods have not been validated by ESDU but contribute to a comprehensive collection of Aerodynamics design information and can be used along side ESDU methods for comparison and analysis to solve design problems. They also provide a possible resource in areas not currently covered by ESDU.
